3. If one liquid is less dense then the others, then it will evaporate quicker.
4. a) Place all of the liquids in separate glasses, each of them should have the same volume of 350 mL
b) Make extra sure that the liquids are of the same volume, and then heat the liquids on the lowest setting of a stove top, all of the liquids at the same time. (Note: the glasses must be stove top safe).
c) Check back in on the liquids in 30 minutes to see how much of the liquids has evaporated.
d) Pour the liquid from the stove top safe bowl into a glass that measures in mL, and see how much the liquid has dropped from the 350 mL that it started with.
e) Record the data that you have collected in the data table.
f) Repeat these steps for six more trials of the same procedure, because it will better verify which of the liquids has evaporated the most, and it should be the same one each time (make sure that the materials you are using are completely cleaned so that they don't interfere with the next trials).

Abstract
For the procedure, five liquids were evaporated to see which one evaporated the most in a certain amount of time. The liquids were put into a stove top pot and put on the lowest setting of heat for thirty minutes. After the thirty minutes were up, the stove was turned off and the liquids were poured back into the measuring glass. The liquids were measured in mL to see how much had evaporated. The liquid that evaporated the most, as an average, was the orange juice. The orange juice had an average of 143.17 evaporated. The liquid that evaporated the least was the salt water, which had an average of 129.67 evaporated. This project can be found on many websites and sources that are very similar to this one.
Problem
Which liquid will evaporate the most in a certain amount of time?
Hypothesis
If a liquid is less dense then another, then it will evaporate quicker.
Experimentation
This project has been done on many levels of complexity, whether on a very simple level, or in great depth. The point of this project is to find out which types of liquids evaporate the most. The experiment is a time consuming one but very effective when it comes to data. The problem and hypothesis are not too complicated in the sense of depth, they are simple but very conclusive. The procedure was one that was not hard to complete, but was very time consuming. The data that was collected helped to conclude a one liquid that evaporated more than the others when it came to averages. All of the equipment that was used worked well to perform the experiment, and there were no problems when it came to the equipment. All of the data that was collected was put into a table that was easy for comparisons and also easy to put into a graph.
Discussion
When analyzing my data, it was concluded that on average, the orange juice had evaporated that most after thirty minutes of heat. According to Figure 1, the water was just short of the orange juice when it came to averages. Since Table 1 shows both the amount that was left after evaporation and the amount that was evaporated, it provides a more accurate analysis. The procedure itself went smoothly, and all of it got done in a matter of about 13 hours total, extending throughout almost 3 nights of experimenting. Since the water was the control group, the only liquid to have surpassed the control was the orange juice, which showed to have evaporated the most out of all of the liquids. This experiment could be improved by going more in depth for the number of liquids and the number of trials for a more accurate experiment. One of the problems was that when the orange juice was being heated, pulp was starting to build up on the sides of the pot, and some of the orange juice could have been absorbed in the pulp instead of evaporating. Another problem was that some of the liquid could have dripped out of the pot when pouring it back into the measuring glass.
Conclusion
The problem was to discover what liquid evaporated the most over a certain period of heating. According to the data that was collected, the orange juice evaporates more than the other liquids that were tested. My hypothesis was that the least dense liquid would evaporate the most. My hypothesis was incorrect because the least dense liquid would be water, and the orange juice averaged out to have evaporated the most. I think that because there is pulp in the orange juice, the orange juice could have been absorbed in the pulp.
Applications
In everyday life, this project could be used for cooking methods in order to evaporate liquids for measurements or what they may have to do with them. The amount that they need could be evaporated in a certain amount of time to evaporate how ever much they want to to get their desired measurement. This could be varied by mixing some liquids to see how much they evaporate together. Also, more trials and liquids could be added to the procedure to get a more accurate look at which liquid would evaporate the most.
